Standard Test Method for Determination of Fracture Toughness of Graphite at Ambient Temperature

Importancia y uso:

5.1 This test method may be used for guidance for material development to improve toughness, material comparison, quality assessment, and characterization.

5.2 The fracture toughness value provides information on the initiation of fracture in graphite containing a straight-through notch; the information on stress intensity factor beyond fracture toughness as a function of crack extension provides information on the crack propagation resistance once a fracture crack has been initiated to propagate through the test specimen.
